Will the 17-Year Cicadas Damage My Trees

Periodical cicadas, sometimes called 17-year locusts, emerge from the ground by the thousands every 13 or 17 years. The cicada nymphs cover trees, shrubs, and other plants, and then molt into adulthood. Adult males congregate in loud choruses, and fly together in search of females. Homeowners may be concerned about damage to their landscapes or gardens. Periodical cicada nymphs feed underground on tree roots, but will not cause significant damage to your landscape trees. In fact, the cicada nymphs help aerate the soil, and bring nutrients and nitrogen to the surface, benefiting plants. Once the nymphs emerge, they spend a few days on trees and shrubs, allowing their new adult exoskeletons to harden and darken. During this time, they do not feed and will not damage your trees. Adult cicadas exist for one reason – to mate. Egg laying by mated females does damage trees. The female cicada excavates a channel in small twigs or branches (those around the diameter of a pen). She oviposits her eggs in the slit, effectively splitting the branch open. The ends of affected branches will brown and wilt, a symptom called flagging. On mature, healthy trees, even this cicada activity should not concern you. Large, established trees can withstand the loss of branch ends, and will recover from the onslaught of cicadas. Young trees, particularly ornamental fruit trees, do require some protection. Because most of its branches are still small enough to attract female cicadas intent on laying eggs, a young tree may lose most or all of its branches. In very young trees with trunks under 1 1/2 diameter, even the trunk may be excavated by a mated female. So how do you keep your new landscape trees safe from cicada damage? If periodical cicadas are due to emerge in your area, you should place netting over any young trees. Use netting with openings less than one half inch wide, or cicadas will be able to crawl through it. Drape the netting over the entire tree canopy, and secure it to the trunk so no cicadas can crawl under the opening. Your netting will need to be in place before the cicadas emerge; remove it once all the cicadas are gone. If you are planning to plant a new tree in a year when cicadas are due to emerge in your area, wait until the fall. The tree will have 17 years to grow and establish itself before the next generation arrives.

What are your responsibilities and obligations as an educator of young children or youth? My responsibilities as an educator is to make sure all children are treating fairly. I must make sure children have a safe place to learn and develop in every area of life. Each child must feel safe and happy while making learning fun and exciting. As, an early childhood educator, it is my responsibility to promote learning through play. I must also encourage independence and creativity. The educator must stimulate intellectual curiosity and understand the world around them. Every educator must understand that each child is different and they all learn on different levels. Each child is different, so teaching should be different. What roles do the parents, school administrators, and community at large play in education? Parents play a large play in the life of their child. Their parent is their first role model. Parents should model a good attitude about learning and that will inspire their child to be positive about their educational journey. A childs first learning starts with the parent. Children begin to learn from the time they are conceived in the womb of the mother. Parents begin to read to their child and let the child listen to music. Mothers even talk to the child in the womb. The parents and the community should make sure children have a safe learning environment. Community is a casual and energetic agency of education. It is defined as a group of families settled together in a particular area with more or less common practices, ideals, ideas, values and culture. There are different agencies that support the community such as: museums, art galleries, libraries, music drama centers, recreation centers, religious and secular institution. The administrator works with the staff to make sure everyone is collaborating and working toward the same common goals and opportunities.

Every educator must understand that each child is different and they all learn on different levels. Each child is different, so teaching should be different. The educator should provide goals with the children abilities in mind and include physical and intellectual accomplishments. Children should be introduced to art, music, pre-math, social-self, pre-reading and kindergarten readiness activities as the child shows interest. The educator should keep the child motivated about learning. What should educators teach children and youth? Educator should teach developmentally appropriate activities that change with the age and experience of the learner. The teacher should take in account of the childs cultural background. Teachers may have to come up with different strategies as to how to teach a child. A formal curriculum should be planned program of objectives, contents, learning experiences, resources and assessments offered by a school. Informal curriculum is not planned, its randomly done. Extra Curriculum Fall outside of the normal curriculum Each one of these curriculums play a vital part in the education of a child. I believe a curriculum should always be in place. The curriculum help the educator to stay focused on what they are teaching the children. It helps to track the childs progress. It will help to determine a childs weaknesses and strengthens. I believe sometimes an educator has to stray away from the curriculum or use another learning tool to help the child to learn the curriculum. I think that the educator should do what is necessary to promote the child in learning. I plan to help each child grow to their full potential in learning and at the same time making learning fun and exciting. What do you value? Should educators teach these (or any other) values? As an early childhood educator, we have an incredible opportunity and power to make a difference in the lives of our students. I value my students present and future education. During the first three years of a childs life, essential brain and neural development occurs. Therefore, children greatly benefit by receiving education before kindergarten. This is a key value that every educator should focus on because our job as an early childhood professional is extremely important.

Course Objectives: This course is about using numbers to make better decisions. The focus will be on â€Å"handson† use of quantitative tools for solution of management problems often involving risk and uncertainty. Speci? c course objectives: (1) Introduce you to practical yet sophisticated tools suitable for modeling and solving complex managerial problems with risky outcomes, and (2) improve 1 your skill and experience with the use of spreadsheet tools for analysis of management decision problems. We will learn to mathematically model business decision problems and apply their analytical skills to realistic business contexts. The material covered is useful for executives in all professional areas of business, including but not limited to accounting, ? nance, marketing, information systems, operations management or any other area where it is important to combine quantitative analysis with expert intuitive judgment. Prerequisite: This course builds upon some rudimentary knowledge of mathematics (probability and statistics) and basic pro? ciency with Microsoft Excel. Required Materials: 1. To purchase the required electronic course pack, go to https://create. mcgraw-hill. com/shop/ and search for the following ISBN number: 1121833926. The course pack contains all required cases and some readings. 2. TreePlan, RiskSim, and SensIt (provided by the MSTM program and downloadable from Compass 2g course website) 3. A laptop and Microsoft Excel 2010 (for Windows) or 2011 (for Mac) installed in your laptop Evaluation Methods: There are four components to the evaluation: Case Summary: Minicase Analysis: Group Project: Final Exam: Cases Summary: Roughly every week, individual case summary assignment(s) are due. We will discuss cases in class, so it is important to read and understand the problems posed by the cases before coming to the classroom. The summary of each case must not exceed one page, and it must be submitted on-line via Compass. (PDF format is strongly preferred). It will be graded on a pass/fail basis. In order to pass a case summary assignment, you must show suf? cient evidence that you have read the case and understood the gist of it. 2 10% 30% 15% 45% Minicase Analysis: Minicase analyses (problem sets) will be assigned roughly once a week and graded. The minicases are designed to help you learn the mechanics of the methods covered in class and to give you an opportunity to apply the concepts in simple and illustrative contexts. Please note that minicase assignments require careful interpretation and analysis of the given problems. Points will be deducted if you misinterpret the information given in the case assignments. Discuss your assumptions and clearly explain your quantitative reasoning. Answers (even correct answers) without logical and quantitative reasoning will not receive credit. Minicase analysis assignments will be posted on Compass. This is sometimes an individual assignment but sometimes a team assignment. Late assignments are generally not accepted. Group Project: In the last week of the course, each team will submit an original minicase. The minicase should be based on a real business situation (in the past, in the present, or in the future) and must be analyzed using one or more of the methods or concepts discussed in this course. If you’d like, you can also add other methodology that is not discussed in class. Each case must consist of two parts. In part 1, a business decision problem must be presented with essential information. It can be a ? ctional situation, but it must be based on a real business situation. Part 1 might look like one of the short cases that we analyze in this course and the text (excluding exhibits) must not exceed 5 pages typed ingle-spaced in 12 pt font. (See Darden’s cases for the document format). In part 2, the solution to the problem posed in part 1 must be given. When you construct the minicase, you should have pedagogical values in mind, i. e. , think of writing a teaching case or an open-book exam for future MSTM students at the University of Illinois. Your submitted wor k will be evaluated based on how well the decision analytical framework is utilized to solve a given (hopefully non-trivial) problem (50%) and its pedagogical value or the practicality of the problem (50%). Final Exam: There will be an in-class 3-hour-long open-book, open-notes, and open-laptops ? nal exam. You are NOT allowed to share your laptops with other students or send/receive emails during the ? nal exam. If you miss the ? nal exam without prior discussions with the instructor or without university-authorized emergencies, then you will receive zero credit. 3 Practice Problem Sets: Practice problem sets and their solution keys will be regularly posted on Compass. They are designed to help you understand the material and to provide practice using various concepts and techniques discussed in class. These assignments will not be collected or graded. However, these problem sets will be helpful for the quiz and the ? nal exam. Some practice problems will be discussed as examples in class. Grades: The ? nal letter grade will be based upon each individual’s level of understanding and learning evidenced by the weighted cumulative points from all four components shown in Evaluation Methods. Laptop and Electronic Communications Policy: You are required to bring your laptop to each class; you will have to use your laptop to download ? es and participate in problem-solving activities in class. You are not allowed to check e-mail or send text messages using your cell phone or laptop. Set your cell phone to silent mode. Academic Integrity and Honor Code: You are expected to behave ethically throughout the term and follow the norms and guidelines outlined by the University on academic integrity. 4 Course Modules: Module 1 Topic Reading Cases Module 2 Topic Reading Cases Module 3 Topi c Reading Cases Module 4 Topic Reading Cases Module 5 Topic Reading Cases Module 6 Topic Reading Cases Module 7 Topic Reading Cases Value of Information and Control Risk Management Harimann International Optional module (if time permitted) Downstream Decisions – Merck Co. ; International Guidance Control Sensitivity Analysis Sensitivity Analysis Using SensIt CyberLab (A), Supp, (B); Liquid Gold Probability Assessment from Historical Data Probability Distributions Commerce Tavern Simulation Analysis Monte Carlo Simulation Using RiskSim George’s Revised Forecast and Addendum Sampling and Statistical Inference – Jade Shampoo (A) and (B) Decisions under Uncertainty DTP Ch.
